A Ground Current Suppression Method for Single-Phase Photovoltaic (PV) Inverters

IEEE Access
For single-phase PV inverter systems, when relays connected to the grid live line are switched on and the DC/AC has not yet entered Pulse Width Modulation (PWM) mode, the ground current is distorted.

Study the Effect of Serial Inductance on Reducing the Current Harmonic Distortion of Three-Phase Bridge Rectifier

Tikrit Journal of Engineering Sciences, 2022
The aim of this paper is to analyze the influence of adding serial inductance in AC side of the 3ph -6 pulse bridge rectifier on the reduction of harmonic distortion rate. A simulated model with serial inductance was analyzed.

Caregiver Perspectives on the Burden of Disease and Treatment in Uncontrolled Gout

Arthritis Care &Research, EarlyView.
Objective Uncontrolled gout (UG) refers to persistently elevated serum urate (SU) levels >6 mg/dL and ongoing gout symptoms despite use of urate‐lowering therapy (ULT). The objective of this study was to evaluate the burden associated with informal caregiving for individuals with UG.

Beyond Visual Scoring: Computational Computed Tomography Analysis for High‐Resolution Computed Tomography–Based Quantification of Interstitial Lung Disease in Inflammatory Rheumatic Disease

Arthritis Care &Research, EarlyView.
Interstitial lung disease (ILD) is a significant cause of morbidity and mortality in patients with inflammatory rheumatic disorders (IRDs). High‐resolution computed tomography (HRCT) is widely considered the gold standard for the noninvasive assessment of ILD; however, its interpretation is constrained by substantial interobserver variability and the ...

Revisiting Stability Criteria in Ball‐Milled High‐Entropy Alloys: Do Hume–Rothery and Thermodynamic Rules Equally Apply?

Advanced Engineering Materials, Volume 27, Issue 6, March 2025.
The stability criteria affecting the formation of high‐entropy alloys, particularly focusing in supersaturated solid solutions produced by mechanical alloying, are analyzed. Criteria based on Hume–Rothery rules are distinguished from those derived from thermodynamic relations. The formers are generally applicable to mechanically alloyed samples.

Commutation Failure Prediction Method Considering Commutation Voltage Distortion and DC Current Variation

IEEE Access, 2019
Commutation failure (CF) at the inverter side is one of the most common failures in the line-commutated converter-based high voltage direct current (LCC-HVDC) system. Effective prediction of CF helps to formulate and implement protection measures timely.
